並列タイトル等Stress Intensity Factor for a Circumferential Crack in a Finite Length Cylinder under Arbitrarily Distributed Stress on Crack Surfaces by Weight Function Method
一般注記A weight function which can be applied in evaluating the stress intensity factor of a circumferential crack in a finite length cylinder under arbitrarily distributed stress on crack surfaces was derived based on the closed form stress intensity factor equation previously developed by the authors. The effects that structural parameters, such as cylinder length, and stress distribution have on the stress intensity factor can be easily evaluated systematically by applying this weight function. The validity of the weight function was confirmed by numerical examples for linear, uniform and quadratic stress distribution. From these examples, the effect that cylinder length has on the stress intensity factors for these stress distributions was quite large, and the weight function derived in this paper will give a practical solution to these problems.
